DETAILED DESCRIPTION OF THE INVENTION

The term “sock” as used herein may include, for example, any suitable sock or garment that is intended for covering the foot (or a portion thereof) or for enclosing the foot (or a portion thereof). Such sock may be of various sizes or dimensions, and may be implemented as, for example, a business sock or formal sock, a casual sock, a sports sock, a training sock, a sock suitable for wearing indoors and/or outdoors, a medical sock, an elastic sock, a knee-high sock, a bare sock or ankle sock, or the like.

Although portions of the discussion herein and/or the drawings may refer, for demonstrative purposes, to a sock worn on the foot, the present invention may further comprise, or may be used in conjunction with, other suitable garments; for example, stockings, lingerie items, hose, hosiery, leggings, soft shoes or fabric-made shoes, or other suitable articles of clothing or items of clothing or garments.

Applicants have realized that a conventional sock includes a conventional toe-box or toe-area, which covers only the toe fingers. In contrast, the present invention comprises a sock having a toe-box or toe-area that is extended backwardly (e.g., towards the ankle, towards the back of the foot) or is elongated backwardly or is enlarged backwardly, and reaches at least or approximately 25% of the foot length, or reaches at least or approximately 33% of the foot length, or reaches at least or approximately 40% of the foot length, or reaches at least or approximately 50% of the foot length, or reaches at least or approximately 51% of the foot length, or reaches at least or approximately 60% of the foot length, or reaches at least or approximately 66% of the foot length, or reaches at least or approximately 70% of the foot length, or reaches at least or approximately 75% of the foot length; or reaches at least or approximately 80 or 85 or 90 or 95 or 99 or 100 percent of the foot length (e.g., optionally reaching the ankle area, or bordering directly with the ankle area, or attaching directly through a single seam or a single hem with the ankle area); or reaches (or covers) approximately between 25 to 75 percent of the foot length; or reaches (or covers) approximately between 25 to 66 percent of the foot length; or reaches (or covers) approximately between 33 to 66 percent of the foot length; or reaches (or covers) approximately between 25 to 50 percent of the foot length; or reaches (or covers) approximately between 33 to 75 percent of the foot length. Other suitable percentage values or ratios may be used, in accordance with the present invention.

In some embodiments, instead of creating a conventional toe-box, a special pre-defined knitting program may be used by a knitting machine in order to separately knit the enlarged fore-foot area, in parallel to or in series with the knitting of other region(s) of the sock.

In accordance with the present invention, the sock may have a toe area without excessive fabric that interrupt between the foot and the shoe; and the sock may lack or may exclude “ears” or “ear portions” that typically exist in a conventional sock in which a seam is present at the front edge of the tow-box, or on top of the toe itself, or under the toe itself. The present invention may allow to create a perfect fore-foot area that may be connected integrally to the central area (the mid-foot area or midfoot area) of the sock as one integrated piece.

In some embodiments of the present invention, the combined toe-area/fore-foot-area may reach backwardly and may cover up to 75 percent of the length of the foot, or even 80 or 90 or 95 or 99 or 100 percent of the length of the foot, almost reaching the ankle area (or actually reaching the ankle area). In some embodiments, for example, in socks that are intended for children or toddlers or infants or babies, or in other small-size socks or “petit” size, the combined toe-area/fore-foot-area may reach the ankle area of the sock, or may reach the ankle, such that the entire combined toe-area/fore-foot-area may be seam-less (or hem-less or stitch-less) and such that a single seam (or hem, or stitch) may exist at or near (or towards, or halfway towards, or two-thirds towards) the ankle area (e.g., under the foot, or over the foot), connecting the combined toe-area/fore-foot-area to the ankle area (or the hindfoot area or the hind-foot area) or to the central area (or the midfoot area or the mid-foot area) of the sock.

Reference is made to FIGS. 1A-1J, which are schematic illustrations of multiple views of a sock 101 having an enlarged or elongated fore-foot area (or, an elongated toe-area, or an elongated combined toe-area/fore-foot-area), in accordance with some demonstrative embodiments of the present invention. Sock 101 may comprise an enlarged or elongated toe area or front area, thereby providing an improved fit or a perfect fit for the foot of the wearer.

Reference is made to FIGS. 2A-2J, which are schematic illustrations of multiple views of a sock 101 having an enlarged or elongated fore-foot area (or, an elongated toe-area, or an elongated combined toe-area/fore-foot-area), in accordance with some demonstrative embodiments of the present invention. Sock 102 may comprise an enlarged or elongated toe area or front area, thereby providing an improved fit or a perfect fit for the foot of the wearer.

Reference is made to FIGS. 3A-3J, which are schematic illustrations of multiple views of a sock 103 having an enlarged or elongated fore-foot area (or, an elongated toe-area, or an elongated combined toe-area/fore-foot-area), in accordance with some demonstrative embodiments of the present invention. Sock 103 may comprise an enlarged or elongated toe area or front area, thereby providing an improved fit or a perfect fit for the foot of the wearer.

Reference is made to FIGS. 4A-4J, which are schematic illustrations of multiple views of a sock 101 having an enlarged or elongated fore-foot area (or, an elongated toe-area, or an elongated combined toe-area/fore-foot-area), in accordance with some demonstrative embodiments of the present invention. Sock 104 may comprise an enlarged or elongated toe area or front area, thereby providing an improved fit or a perfect fit for the foot of the wearer.

Socks 101-104, and particularly sock 102 and/or sock 104, demonstrate a sock having a non-symmetrical (and optionally extended or enlarged or elongated) split-toe area, in accordance with some demonstrative embodiments of the present invention. Each sub-area of the toe-area (or, of the combined toe-area/fore-foot-area) may optionally have different properties, colors, fabric type, fabric processing type, finishing, patterning, and/or other features. The sock may comprise an enlarged or elongated or extended toe area (which may be split or divided as shown), thereby providing an improved fit or a perfect fit for the foot of the wearer.

In some embodiments, the elongated toe-area may be formed as a non-symmetrical trapezoid, in contrast with conventional socks which may have a symmetrical trapezoid toe-area. Applicants have realized that the non-symmetrical toe-area may better hold or grasp the foot or the toes, and may provide an improved fit and greater convenience to the wearer. Optionally, the toe-area may be elongated or extended or enlarged, extending downwardly toward the heel area, and occupying an area having a length that is at least 1.5 times or 2.0 times relative to the length of the big-toe itself. The extended toe-area may be implemented as a seam-less region, free of any seams or stitches or stitching.

In some embodiments, the extended or elongated toe-area (which may be a split-toe area, namely a toe-area divided into two or more regions; or may be a unified un-divided toe-area) may have one or more properties which may differ from properties of other areas of the sock; for example, three-dimensional (3D) knitting or patterning, design knitting, stripes, lines, rows, columns, shapes, design knitting in a particular shape, logo, branding, holes, macro-vent, ribs, plain knitting, cushioning knitting; utilization of different fabric(s), or fabric type(s), or type(s) of processing of fabrics; utilization of different colors, fabric finishing, fabric processing; different elasticity, rigidity, flexibility, rigidness, stiffness; different number of lines of fabric, or threads, or thread-count or line-count; different fabric effects (e.g., towel style), or the like. Such properties may be implemented in the toe-area (or in the split-toe area, or in a sub-division of the split-toe area) in a particular manner which may differ from other regions(s) of the sock.

Reference is made to FIGS. 5A-5C, which are schematic illustration of six socks 3201-3206; the first sock 3201 being a prior art sock, whereas the other socks 3202-3206 are socks in accordance with some demonstrative embodiments of the present invention.

Conventional sock 3201 may have a short toe-area, which may only partially cover the big toe (indicated with an oval). The short toe-area may be a symmetrical trapezoid or an isosceles trapezoid. Typically, up to 90 lines or threads may be comprised in the short toe-area of conventional sock 3201. A seam or stitch or hem typically exists over or across the toes, or over the big toe; or under the toes, or under the big toe.

Sock 3202 may have a short toe-area; but the short toe-area may be a non-symmetrical trapezoid, providing an ergonomic structure and improved fitting; and enabling to include up to 140 lines or threads in the short toe-area; and avoiding undesired “ears” or excess fabric (e.g., not occupied by human toes) that often exist in conventional socks. In some embodiments, up to 140 lines or threads may be comprised in the short toe-area of sock 3202.

Sock 3203 may have an elongated toe-area which extends backwardly towards the heel and covers the fore-foot area, thereby creating a unified component of toe-area/fore-foot-area. The elongated combined toe-area/fore-foot area may cover the entire human big toe; and may cover, or may reach until, approximately 25% or 30% or 33% or 40% or 50% of the entire length of the foot-area of the sock. This structure may thus obviate the need to have a seam or a stitch that is located over or under the human toes in conventional sock 3201. For demonstrative purposes, the ending of the combined toe-area/fore-foot area may be symmetrical trapezoid or isosceles trapezoid. In some embodiments, around 250 or 280 or 300 (or more than 300) lines or threads may be comprised in the elongated toe-area/fore-foot-area of sock 3203.

Sock 3204 may combine the novel features of sock 3202 with the novel features of sock 3202. For example, sock 3204 may have an elongated toe-area which extends backwardly towards the heel and covers the fore-foot area, thereby creating a unified component of toe-area/fore-foot-area. The elongated combined toe-area/fore-foot area may cover the entire human big toe; and may cover, or may reach until, approximately 25% or 30% or 33% or 40% or 50% of the entire length of the foot-area of the sock. This structure may thus obviate the need to have a seam or a stitch or a hem that is located over or under the human toes in conventional sock 3201. Furthermore, the ending of the combined toe-area/fore-foot area may be non-symmetrical trapezoid, providing ergonomic structure and improved fitting. In some embodiments, around 250 or 280 or 300 lines or threads may be comprised in the elongated toe-area/fore-foot-area of sock 3204.

Sock 3205 may be generally similar to sock 3204, but may feature a split-toe structure; such that the elongated combined toe-area/fore-foot-area may be divided or split into two (or more) sub-areas. Sock 3205 may have an elongated toe-area which extends backwardly towards the heel and covers the fore-foot area, thereby creating a unified component of toe-area/fore-foot-area. The elongated combined toe-area/fore-foot area may cover the entire human big toe; and may cover, or may reach until, approximately 25% or 30% or 33% or 40% or 50% of the entire length of the foot-area of the sock. This structure may thus obviate the need to have a seam or a stitch or a hem that is located over or under the human toes in conventional sock 3201. Furthermore, the ending of the combined toe-area fore-foot area may be non-symmetrical trapezoid, providing ergonomic structure and improved fitting. In some embodiments, around 250 or 280 or 300 lines or threads may be comprised in the elongated toe-area fore-foot-area of sock 3205.

Sock 3206 may be generally similar to sock 3202, but may feature a split-toe structure; such that the short toe-area may be divided or split into two (or more) sub-areas. The short toe-area may be a non-symmetrical trapezoid, providing an ergonomic structure and improved fitting; and enabling to include up to 140 lines or threads in the short toe-area; and avoiding undesired “ears” or excess fabric (e.g., not occupied by human toes) that often exist in conventional socks. In some embodiments, up to 140 lines or threads may be comprised in the short toe-area of sock 3206.

Reference is made to FIG. 6, which is a schematic illustration of a sock 2100, in accordance with some demonstrative embodiments of the present invention. Instead of having a small convention toe-area 2101, the sock of the present invention may comprise an enlarged toe-area that includes both regions 2101 and 2102. Similarly, instead of the conventional toe-area 2101 that borders an adjacent area 2103, the sock of the present invention may comprise an enlarged toe-area 2101-2012 that borders an adjacent enlarged area 2103-2014.

Line A-B may indicate an optional seam or hem that connects or attaches the front area or the fore-foot area of the present invention (which comprises areas 2101-2104) with the main area 2105 of the sock (which may optionally comprise a heel-area 2106). Line A-B may be a visible seam, or a visible line; or may be an invisible seam, or an invisible line.

Line E-F may indicate an optional seam that connects or that borders between the enlarged (or elongated) toe-area 2101-2012, and its adjacent enlarged area 2103-2104. Line E-F may be a visible seam, or a visible line; or may be an invisible seam, or an invisible line.

Line C-D, as well as points H and F, are denoted in the drawing for demonstrative purposes only and in order to emphasize some of the unique features of the present invention relative to conventional sock; and they need not be comprised (or be visible) in sock 2100 of the present invention.

An arrow 2191 demonstrates the length of the novel, elongated toe-area of sock 2100; in contrast with a nearby arrow 2192 which indicates the length of a convention prior-art sock.

Reference is made to FIG. 7A, which is an illustration of a front-area of a prior art sock 2201; shown in contrast with FIG. 7B, which is an illustration of a front-area (or toe-area) of a sock 2202 in accordance with some demonstrative embodiments of the present invention, demonstrating the elongated or enlarged toe-area that the present invention may provide.

FIGS. 7A-7B further demonstrate, for example, that the sock 2202 of the present invention has a more elongated structure, which may allow an improved fit (or grasp) on the wearer's foot; and may lacks “ears” or “ear regions” that the convention sock 2201 may include.

FIGS. 7A-7B further demonstrate, for example, that the slopes or slanting of the front-area of the conventional sock 2201 are approximately 45 degrees; whereas the slopes or slanting of the front-area of the sock 2202 of the present invention are different, and may be significantly reduced (e.g., a slanting of 10 or 15 or 20 or 25 or 30 degrees, relative to the long axis of the sock).

Reference is made to FIG. 8A, which is a schematic illustration of a conventional sock 2301 having a conventional toe-area 2311; and to FIG. 8B, which is a schematic illustration of a sock 2302 having an enlarged or elongated toe-area 2322 in accordance with some demonstrative embodiments of the present invention.

As demonstrated in FIG. 8A, the conventional sock 2301 has toe-area 2311 which may cover the five toes of the foot but may leave excess fabric protruding sideways relative to the toes, or excess “ears” or “ear regions” there. Furthermore, in the conventional sock 2301, the conventional toe-area 2311 requires a connecting seam to be exist over the toe(s) and/or under the toe(s), thereby creating undesired friction in that area. The conventional sock 2301 fails to provide continuity of the fabric from the front-side or front-edge of the sock 2301 (or the foot), towards and through-out the fore-foot.

As demonstrated in FIG. 8B, the sock 2302 of the present invention may comprise an elongated toe-area 2322 which may seamlessly continue as a continuous or seamless fabric through or until, approximately, the center of the foot (or the sock), rather than having a toe-area that abruptly terminates (e.g., with an uncomfortable seam) immediately as the toes themselves end. The present invention thus allows to continuously connect the center-foot area, with the elongated or enlarge toe-box area, thereby creating an ergonomic structure with improved fit around the wearer's foot, and without the undesired feel or look of excessive “ears” fabric(s). The present invention allows continuous knitting of the foot-center area as a continuous extension of, or a seamless extension of, the toe-box area (or vice versa), without a bordering seam that needs to exist over the toe(s) or under the toe(s). Optionally, a connecting seam may be used, for example, over or under the center of the foot (or the sock), to connect the fore-foot area with the back-foot area.

Reference is made also to FIG. 8C, which is a schematic illustration of sock 2302 having enlarged or elongated toe-area 2322 in accordance with some demonstrative embodiments of the present invention, demonstrating how the sock 2302 may fit over a foot of a wearer. The five top ovals or ellipses indicate the five toes of the foot (big toe; second toe; third toe; fourth toe; little toe); the “P” denotes a location of a phalanx, or a location of a set of three phalanges of each toe (e.g., each “P” denoting a set of distal phalanx, middle phalanx, and proximal phalanx); the “MB” denotes a location of metatarsal bones, of which two are shown (rather than five) in order to avoid over-crowding of the drawing; the “MT” denotes a location of metatarsophalangeal joint(s) (showing only two instead of five, to not over-crowd the drawing); the “TM” denotes a location of tarsometatarsal joint(s) (showing only two instead of five, to not over-crowd the drawing).

In accordance with some embodiments of the present invention, the elongated toe-box or toe-area, and/or the non-symmetrical toe-box or toe-area, may cover an entirety of all lengths of all the phalanges of the foot; and may cover all the metatarsophalangeal; and may optionally extend backwardly towards the ankle and may cover also a portion (but not all) of the metatarsal bones.

In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 25 to 50 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 30 to 50 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 33 to 50 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 40 to 50 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 25 to 45 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 30 to 45 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 33 to 45 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 33 to 40 percent of the entire length of the foot. In some embodiments of the present invention, toe-box or toe-area or fore-foot area may cover, for example, between 25 to 33 percent of the entire length of the foot. Other suitable ratios or dimensions may be used.

Reference is made to FIG. 9A, which is a schematic illustration of a conventional knitting scheme 2401 for a conventional sock; and to FIG. 9B, which is a schematic illustration of a knitting scheme 2402 for a sock in accordance with some demonstrative embodiments of the present invention.

As demonstrated in FIG. 9A, in the conventional knitting scheme 2401, each two lines are formed by using the same number of needles; and the knitting scheme 2401 is structured by utilizing a repetition of two-line cycles, thereby allowing to include up to 95 or 100 lines in the toe-box areas.

In contrast, as demonstrated in FIG. 9B, the knitting scheme 2402 of the present invention may utilize varying needle selection cycles, for example, having eight lines per cycle of needle selection. This may enable creation of the elongated or extended or enlarged toe area, which may include approximately 250 or 260 or 270 or 280 or 290 or 300 lines, or over 200 lines, or over 250 lines or over 300 lines (e.g., of threads of knitted fabric), thereby providing higher resolution or finer resolution to the fabric or the extended toe-box area.

In some embodiments, for example, the top half of knitting pattern 2402 may correspond to the area that covers the top-side of the toes and fore-foot; whereas the bottom half of knitting pattern 2402 may correspond to the area that covers the bottom-side of the toes and fore-foot. The two halves of knitting scheme 2402 may be generally similar, or may be substantially symmetrical to each other, or may be mirror image of each other.

Reference is made to FIG. 10, which is a schematic illustration of a sock 2501 in accordance with the present invention. The sock 2501 may comprise a unified, continuous- fabric, seamless region, that extends from point E at the front of the sock, extending backwardly towards the center of the foot, reaching the line (or the seam) denoted A-B. This extended or elongated or enlarged or combined or unified toe-box/fore-foot area, from point E to line A-B, may be substantially longer or larger (e.g., two or three times longer or larger) relative to a conventional, small, toe-box area that typically extends from point E to broken line C-D. Additionally, in the sock 2501 of the present invention, there may be no seam(s) at all within the combined elongated fore-foot/toe-box area (from point E to line A-B); instead of having a seam at line C-D in a conventional sock.

Reference is made to FIG. 11, which is a schematic illustration of a sock 2601 in accordance with the present invention. The sock 2601 may comprise a unified, continuous-fabric, seamless region, that extends from the front edge of the sock, extending backwardly towards the center of the foot, reaching (without any seams) approximately one-third or one-half or two-thirds of the length of the foot. This extended or elongated or enlarged or combined or unified toe-box/fore-foot area, shown in darker shade in FIG. 26, may be substantially longer or larger (e.g., two or three or four times longer or larger) relative to a conventional, small, toe-box area that typically extends only until a portion of the toe or until the entire length of the toe itself, and not beyond the toe. Additionally, in the sock 2501 of the present invention, there may be no seam(s) at all within the combined elongated fore-foot/toe-box area (the darker shade); instead of having a seam at or under (or on top of) the toe itself in a conventional sock.
